v end of arm I2 to impinge the upper edge of the i 2 Claims This invention relates to a combinationhand saw and try square, and has particular` reference to'a nov to the handle of a hand'saw and to coact with I, the saw blade to provide, in connection .with the; i

back edge of the saw blade, a tryV square.

.The primary objectfof the presentfinvention is to provide a combination ytool of the above kind which is simple in.V construction, efficientfin; use, and economical toA produce.

A further object of the invention is to pro- A vide a simple device of the above kind that may vbe readily applied to a hand saw to provide a v tool of the kind set forth, and vthat'l may be: readily adjusted to-the properv positio n relativel to the saw blade.

In the drawing: .Yv n Y Figure 1 is a fragmentary side elevational .view of a handsaw. equippedl with Va devicef` constructed in accordance with vthepresent. inven-.

Ais a topr plan view thereof.

Figure 2 v Figure 3 is' a V.vertical sectionv takenv online e Figure 4 is aperspective view 'ofwthe device Referring in detail tothe drawing,=f5xdesig v natesthe bladeof a conventional-handsaw `and 6 the v handle thereof having a slot Vmid-Waybe tween the sides and in one end thereof in which the rear wider end of the bladeis ASeliil'led by the usual bolts fl... The 'blade 5fhas a straight backed'ge 8.

In accordance with -the present invention, a special device is applied to the saw'handle' and coacts with .the saw VVblade 5 to provide a. try square.v This device consistsy of a right angular channel member 9, one arm I0 of which is.longi;` r'tudinally slotted at II midway between the ,sides thereof to straddle and snugly receive the saw blade 5, the other arm I2 of member 9 snugly fitting over the upper edge portion of the saw handle 6 and having depending eark extensions I3 on the side iianges thereof. Screws Il or the like vpass through the earextensions I3 to pivotally secure the member Sto the handle 6.

el device adapted to be applied.

saw handle 6, and' this set screw is used to advjustably swing the member 9 about the pivotal pointprovided by screws I4 so as to place rthe spring extension I5 under considerable tension blade 5 located forwardly of said arm I0.

: 1 ,Inusing the tool in one well known way, the

portion of arm I0 at .either side of the saw blade 5 may. be disposedzagainst a side edge of a board,

vand me bak'edge s of the saw blade s will extend across the board at atrue right angle to jsaid side edge andthe arm I0. Thus, the back edge of the 'saw blade may be used as a straight :edge to'mark a line across the board for use asl a guide in sawing vthe board to a desired length'andalo'ng a transverseline ai'. a right angle to the side edge of the board.

vIt* will be seen that the invention is simple,

i efficient, and otherwise adapted to meet with the vrequirements for successful commercial use.. Aj

jamb nut II` secures the screw I6 in adjusted position.

What I.c1aim is:

. 1. In combinationwith v a hand saw embody 'ing a ,blade having a straight back vedge. and va'. slotted handle having an end of the blade se-I cured in the slot thereof, a right angular channel member, one arm of said channel member having 'a lcentral. longitudinaly slot receiving the sawV blade, `the other farm of said channel member tting over-thelupper edge ofthe saw han-V dle and having depending ear extensions'on the side flanges thereof, means passing through said ear extensionsto pivotallysecure said-channel member to the sawjhandle-a rearward resilient leaf spring extension on the web f said other arm bearing on the upper edge of the saw handle and" tensioned to` engage said Vedge when the one arm of said channel memberr is disposed at an obtuse angle to the back edge of the saw'blade, and means to swing said channel The arm l2 has a rearward resilient leaf spring .memberrelative to the saw handle to increase the tension of said spring extension and dispose said'one arm at a righi; angle to the back-edge of the saw.

2, The.v construction set forth in claim 1, wherein said means consists of a set screwadjustably threaded through said other arm forwardly of said'ear extensions and imping'ing the .upper ,edge kof the saw handle.
